1. Radiators should not be in contact with any acid, alkali or other corrosive properties.

2. It is suggested that soft water should be used. Hard water should be softened to avoid blockage and scaling in radiator.

3. Use antifreeze fluid. In order to avoid the corrosion of radiators, it is necessary to use long-term antirust and antifreeze fluid manufactured by regular manufacturers and in line with national standards.

4. In the process of installing the radiator, do not damage the radiator ribbon (sheet) or touch the radiator, in order to ensure the cooling capacity and sealing.

5. When the water is completely released in the radiator and then injected, the water release switch of the engine cylinder block should be turned on first, and then closed when there is water flowing out, so as to avoid blisters.

6. Water level should be checked at any time in daily use, and water should be added after shutdown and cooling. When adding water, the cover of the water tank should be opened slowly, and the operator’s body should be as far away as possible from the nozzle, in order to prevent the high-pressure steam from ejecting from the nozzle causing scald.

7. In winter, in order to prevent core rupture caused by ice, if long-term parking or indirect parking, water tank cover and water discharge switch should be put out.

8. The effective environment of the spare radiator should be kept ventilated and dry.

9. According to the actual situation, the user should clean the core of the radiator completely within 1-3 months. When cleaning, rinse with clean water along the side of the reverse inlet air.

10. The water level gauge should be cleaned every 3 months or, depending on the actual situation, the components should be removed and cleaned with warm water and non-corrosive detergent.
